Preparation of Carbon Nanotube Growth Catalyst: RF magnetron sputtering or thermal evaporation is used to deposit a first aluminum thin film (10–20 nm) on a SiO₂ (200 nm)/Si wafer. The aluminum film is oxidized at 600–700°C in air to form an alumina support film. An ultrathin iron film is then deposited by electron beam evaporation onto the alumina and thermally oxidized at 600°C for approximately 10 min in air to form an ultrathin iron oxide film. The resulting catalyst film thickness is measured to be between 0.5 and 0.8 nm.

Preparation of Carbon Nanotube Growth Catalyst: RF magnetron sputtering or thermal evaporation is used to deposit a first aluminum thin film (10–20 nm) on a SiO₂ (200 nm)/Si wafer. The aluminum film is oxidized at 600–700°C in air to form an alumina support film. An ultrathin iron film is then deposited by electron beam evaporation onto the alumina and thermally oxidized at 600°C for approximately 10 min in air to form an ultrathin iron oxide film. The resulting catalyst film thickness is measured to be between 0.5 and 0.8 nm.
